I agree. Isn't there a hidden preference to make that setting stick?

Re: [Talk-us] Center turn lane mapping

[Tod Fitch]

I switched from using the centre_turn_lane tag to using the turn:lanes tagging 
when I discovered the turn lanes plugin for JOSM. Between that plugin and the 
change:lanes plugin I think it is much easier and clearer to tag lanes, 
including center turn lanes, that it was not too long ago.

Only real complaint I have with the turn lanes plugin is that I prefer to have 
tag values of the form “left|none|none|right” rather than “left|||right” as it 
is easier for a human to read. Or at least easier for me to read. You need to 
check a box that does not stay checked between editing sessions for it to use 
“none". And it doesn’t put “none” in all the lanes if there are more than a 
couple of lanes in the same direction.

Re: [Talk-us] Great Lakes missing after osmosis update (diffs installation)

[Pilon, Michel (SSC/SPC)]

Thanks for responding Kevin,

Actually I have the issue after daily updating the whole planet.

But effectively, I don’t have that issue when I use only Ontario province or 
all Canada with geofabric daily updates…

Only with the whole planet daily update…. (same issue with hourly and minutely 
updates).

I am using a 32-cores server with 62 GB RAM and 1.4TB SSD.

ALL: Am I the only one downloading the whole planet and trying to daily update 
it successfully?

Please share your experience if you update the whole planet daily, hourly or 
minutely…

Thanks,

Michel

[Talk-us] Center turn lane mapping

[Martijn van Exel]

Hi all,

I had a discussion about center turn lane mapping with my team this
morning, and I wrote a diary about it proposing one consistent scheme to
tag them. Not a new scheme, but using the existing lanes / turn:lanes
schema as already implemented by the JOSM plugin, in favor of the
centre_turn_lane tag. The diary is here:
https://www.openstreetmap.org/user/mvexel/diary/42432

If you could take the time to share your opinion there I would surely
appreciate it!

Thanks,

Hello Kevin,

Have you gotten a chance to validate the coastlines of the Great Lakes during 
the last weekend?
You’re the only one who responded to my “help” request….

Hello all,

I am in the process of putting in place a local OSM server.

Last Thursday September 21st I populated my PostGIS database using the 
following command:

osm2pgsql --create --slim --flat-nodes /data/osm/pgload/flat_nodes.bin \
 -C 27000 --number-processes 8 --hstore \
 --style /data/osm/openstreetmap-carto-3.2.0/openstreetmap-carto.style \
 --multi-geometry /data/osm/new_planet-latest.osm.pbf

Once done I verified the slippymap and I can see correctly all the Canadian/US 
Great Lakes.

So I applied the daily updates on the data using osmosis (daily diff).   Once 
completed, everything looks good EXCEPT that there is no more water on Great 
Lakes except Lac Érié and Ontario for ALL ZOOM LEVELS. Superior, Michigan and 
Huron Lakes just disappeared!

For the update process, I am using /usr/bin/openstreetmap-tiles-update-expire 
with the followng options for osm2pgsql command:
   OSM2PGSQL_OPTIONS="--number-processes 8 --hstore -C 27000 
--style /data/osm/openstreetmap-carto-3.2.0/openstreetmap-carto.style 
--multi-geometry"

I am using mapnik with openstreetmap-carto stylesheets.

I am really stuck and need help as I tried it 3 times, always with the result 
of Lakes disappearing for all zoom levels… ☹

Any ideas???

Thanks in advanced for your very appreciated help….



Someone probably broke the coastline again. It's easy to goof when editing the 
lake shore.
I don't have time to look into it right now, I can try on the weekend if 
someone else doesn't fix it first.
(And, I confess, I've broken the lake shore of Lake Ontario at least once.
I fixed it promptly once I realized the problem.)

[Talk-us] GNIS Issues to be aware of (was: dubious church node)

[Mike Thompson]

Here are a few other GNIS issues to be aware of:

1) Duplicates  - As someone else pointed out, the GNIS points were
digitized off of the USGS topo maps.  If a feature is actually in multiple
map sheets (such as a mountain), it may appear multiple times. I believe it
was done by state, so if a feature appears in multiple states there will be
multiple entries in the GNIS (sometimes with slightly different names).  I
have pointed out a large number of such cases to the Board on Geographic
names, but that was after the import to OSM, so you may still encounter
them.

2) Classification - It seems that the GNIS used an automated query to
classify some of the GNIS points.  For example, a "park", particularly in
the western US, can be a broad flat relatively treeless valley. Many of
these types of parks were mis-classified in the GNIS as the recreational
type of park.  I pointed out some of these to the Board on Geographic
names, but again, that was after the import.

[Talk-us] Whole-US Garmin Map update - 2017-10-01

free to ask.  However, please do not send me private mail.  The
odds are, someone else will have the same questions, and by
asking on the talk-us@ list, others can benefit.

FAQ



Why did you do this?

I wrote scripts to joined them myself to lessen the impact
of doing a large join on Lambertus's server.  I've also
cut them in large longitude swaths that should fit conveniently
on removable media.  

http://daveh.dev.openstreetmap.org/garmin/Lambertus/2017-10-01

Can or should I seed the torrents?

Yes!!  If you use the .torrent files, please seed.  That web
server is in the UK, and it helps to have some peers on this
side of the Atlantic.

Why is my map missing small rectangular areas?

There have been some missing tiles from Lambertus's map (the
red rectangles),  I don't see any at the moment, so you may
want to update if you had issues with the last set.

Why can I not copy the large files to my new SD card?

If you buy a new card (especially SDHC), some are FAT16 from
the factory.  I had to reformat it to let me create a >2GB
file.

Does your map cover Mexico/Canada?

Yes!!  I have, for the purposes of this map, annexed Ontario
in to the USA.  Some areas of North America that are close
to the US also just happen to get pulled in to these maps.
This might not happen forever, and if you would like your
non-US area to get included, let me know.
